"We're going to be doing it for a while," said East Precinct Lt. Sonya Stewart. "It's for high visibility, but we're also hoping people will come forward and talk to the officers, maybe tell them what they've heard, so that we can find out who killed that little boy."

The incident happened Saturday night about 8 p.m. as people were leaving a community event in the Marks Village neighborhood. Two adult females were grazed by gunfire, and a 2-year-old was shot in the leg.

Police will not release the names of those gunshot victims.

Deonte Mixon was running alongside his 20-year-old mother, Tanisha Glenn, who was carrying her 6-month-old daughter, after the gunfire rang out.

"She saw him hit, and then run back over again because the vehicle had run up on the curb," said Myra Glenn, Tanisha Glenn's grandmother. "It's just horrible."

Myra Glenn said Deonte, her great-grandson, was a playful little boy. "He always wanted to hit grandma and then run," she said. "He wanted you to chase him. He was just a sweet baby."

Tanisha Glenn's father, Theo Scott, said gunfire erupted again Sunday night in the neighborhood, prompting his daughter to move away for the night.

"All these people stand around and see the things happening here and do nothing," Myra Glenn said. "They become part of the problem when they could be the solution."

Myra Glenn said she does believe police will find out who struck and killed Deonte.

"Everybody is praying for my granddaughter and her family, but I also want them to pray for that young man and his family," she said. "He's probably afraid to come forward because he thinks someone will do something to him."
